Once you worked out the puzzle add xxx together for each town and use the formula below to work out where the cache is located. I actually work near there, but you don't have to enter any private property to obtain the cache. It is on a busy road so please be careful if children are with you, and the utmost stealth is required as the muggle population will be high depending on what time of the day you go. The cache is disabled friendly.
The cache is located at the following coordinates:
N51 30.(Slough - Abingdon) (Eastbourne ÷ Clitheroe) (Andover - Bath)
W000 35.(Pontypool - Winchester) (Ipswich ÷ Cambridge + 1) (Redruth - 2)
